To aZZ wh-om it may concern:

Twyers, of which the following is a speci- -iicat1om-- The presentinvention relates to improvements in injector twyers and has for itsprimary object the provision of a device to be used in connection with ablast or smelting furnace for feeding flue dust, smoke, gases and otherproducts of combustion, a second time to thefurnace for thoroughconsumption.

With this end in view the device consists of an injector through which ablast, preferably of air, is fed, and a suction pipe in communicationwith the furnace through which the products of combustion are drawn bythe blast, and the invention further consists in cert-ainrnovel featuresof construction and combinations and arrangements of parts of thisdevice as will be hereinafter described and more particularly pointedout in the claims. r

In the accompanying drawings 1 have illustrated one example of thephysical embodiment of my invention constructed and applied to a furnaceaccording to the best mode I have so far devised for the practicalapplication of the principles.

In the drawings: igure 1 is a vertical longitudinal section of theinvention, and Fig. 2 is a vertical transverse view taken at line 22Fig. 1.

In the practical embodiment of my invention I employ a casting or casing1 of tubular form having an enlarged globular" portion 2, forming aspace or chamber This outer casing l is iutcriorly threaded to receivethe exterior threads 4: of the inner tube 5, which tube is formed at itsrear end with a hexagonal nut portion 6, by means oftube 5 has a seriesof openings 12 around its perimeter through which communication providedbetween the air blast pipe and the interior of the tube the :tube 5 isformedwith 'a tapering nozzle 18, which projects through the spaco3 ofthe outer casing, and is in line with an open- M: v in tho :i'urn anowall ind ica'ted: at 1 Ft The outer casing is also provided with atapered end 16 concentric with the nozzle 13, and between the interiorof the outer cas ing and the exterior of the nozzle 13 a reduced space17 is formed, which opens to the inlet 14E. The tapered end of the outercasing is formed with an-annular l8 and is attached to the furnace wallby suitable mcans, bolts being shown in this instance.

A flanged upstanding tubular pipe 19 forms a means of attachment for thesuction pipe 20, and the flanges are secured together by means of bolts21.

Directly beneath the center of the globular chamber 3 an opening 22,normally closed by a screw cap 23, is formed, a clean out, or in someinstances a second suction pipe may be attached here.

A peep hole is provided at the rear of the inner tube, the mica orisinglass disk 24-. being clamped between the perforated nut 25 and anopening 26, whose walls are screw threaded to receive the cap or not 25.

Assuming the pipes 10 and 20 are connected respectively to blastand tothe combustion chamber of the furnace, a current of air, it such isused, passes through At itstorward end the pipe 10, openings 12, nozzle13, and

through the opening 1%. This passage of air causes suction through, thechamber or space 17, chamber and suction pipe 20. As the blast causesthe passage or a suction current through pipe 20, the flue smoke, dust,gases etc. are drawn through thc'suction connections and are blown intothe furnace, for thorough consumption, as will be understood.

By means of the nut 6 and threaded connection between the outer andinner tubes of the injector, the space 17 at its connection with theinlet 14; may be enlarged or decreased to suit different conditions ofuse.

From the above description taken in con nection with the drawings it isevident I have produced a device which will effectually carry out thepurposes set forth as the object of my invention Having thus fullydescribed my invention, what I claim as new and desire to secure byLetters Patent is:

1. The combination with an outer casing having a short tapered endterminating in a flange, a globular chamber in the casing adjacent tothe tapered end, a small globular chamber at the. other end of thecasing, a blast pipe in communication with the small chamber, a suctionpipe in communication with the large globular chamber, means on saidchamber providing connections for a second suction pipe, an inner casinghaving threaded engagement at one end with the outer casing, a longtapered nozzle formed on the other end of the inner casing, portsa'tlording communication between the blast pipe and the inner casing,and integral adjusting means on the casing'having means thereinpermitting the operator to look into the casing when the device is inoperation.

2. The combination 'with an interiorly threaded open ended outer casingformed with a globular chamber and tapering end, a suction pipe incommunication with said chamber; of an ,inner exteriorly threaded tubehaving integral adjusting means formed with means permitting a view ofthe inside of the tube at all times, said tube being formed with atapering nozzle in the tapering end of the outer casing and ports at therear of the nozzle, and an annular chamber in the outer casingsurrounding said ports and connected with a blast pipe, the adjustmentof said inner tube serving to Vary the passage from the casing to thefurnace.

In testimonywhereof I ailix my signature, in presence of two witnesses.
